[CMake] Problems with coverage on OS X Server

[NoRulez]

I've found this http://stackoverflow.com/questions/7031126/switching-between-gcc-and-clang-llvm-using-cmake

Is this all which I need to configure or did you do something different/special?
Please could you post your settings to use clang instead of gcc on OS X

Thanks in advance

Best Regards
